Asahi Glass develops production method for thinner glassubstraten

Asahi Glass, maker of glassubstraten for displays, has a new processing method for thin glassubstraten developed. The glass with thicker glass, laminated, so that existing production lines can be used.

The Japanese manufacturer of glassubstraten had last year, the 0.1 mm thin glass developed, but its application through the so-called roll-to-roll method resulted in another problem, because displayfabrikanten do major changes to their production lines were required to make. To the acceptance of the extremely thin glass substrate to accelerate has Asahi Glass a new method developed to allow the glass using the more common sheet-to-sheet method, displays can be processed.

The 0.1 mm thin glass for the duration of the production is laminated on a 0.5 mm thick moederglas, with the help of a special interface. By this layer is the laminated glass is highly resistant to heat and chemical treatments during the production of displays take place. The thicker glass cover also prevents the surface of the ultra-thin glass substrate during the production was damaged. According to the Japanese manufacturer, it is draagglas at the end of the production process is easy to remove.

According to Asahi Glass has a 0.1 mm thin glass substrate is not only good properties in terms of transparency, hittevastheid and electrical shielding, but it is glass because of its thinness also more flexible than thicker glass and thinner displays to produce. Asahi Glass plans to have a sample of the laminated substrate to show at the 2012 SID International Symposium, a displaybeurs this week in Boston takes place.
